Airworthiness Directive · Amendment 39-19030 · Landing gear
Airbus Airplanes
This AD applies to the airplanes identified in paragraphs (c)(1), (c)(2), (c)(3), and (c)(4) of this AD, certificated in any category, all manufacturer serial numbers.
(1) Airbus Model A318-111, -112, -121, and -122 airplanes.
(2) Airbus Model A319-111, -112, -113, -114, -115, -131, -132, and -133 airplanes.
(3) Airbus Model A320-211, -212, -214, -231, -232, and -233 airplanes.
(4) Airbus Model A321-111, -112, -131, -211, -212, -213, -231, and -232 airplanes.
We are superseding Airworthiness Directive (AD) 2017-13-12, which applied to all Airbus Model A318 and A319 series airplanes; Model A320-211, -212, -214, -231, -232, and -233 airplanes; and Model A321- 111, -112, -131, -211, -212, -213, -231, and -232 airplanes. AD 2017- 13-12 required modification or replacement of certain side stay assemblies of the main landing gear (MLG). This new AD clarifies the formatting of a figure in the published version of AD 2017-13-12. This new AD was prompted by reports indicating that affected parties misinterpreted the applicability of the affected part numbers due to the formatting of a figure in the published version of AD 2017-13-12, which could result in a negative effect on compliance. We are issuing this AD to address the unsafe condition on these products.
This paragraph restates the requirements of paragraph (g) of AD 2017-13-12, with revised figure formatting. Within 120 months after August 9, 2017 (the effective date of AD 2017-13-12), accomplish the action specified in paragraph (g)(1) or (g)(2) of this AD.
(1) Modify each MLG side stay assembly having a part number listed in figure 1 to paragraphs (g), (h), and (i) of this AD, in accordance with the Accomplishment Instructions of Airbus Service Bulletin A320-32-1429, Revision 01, dated February 29, 2016, and the service information specified in paragraph (g)(1)(i) or (g)(1)(ii) of this AD, as applicable. The modification may be done “off wing,” provided the modified MLG is reinstalled on the airplane.
(i) For Model A318 series airplanes; Model A319 series airplanes; and Model A320-211, -212, -214, -231, -232, and -233 airplanes: Messier-Bugatti-Dowty Service Bulletin 200-32-315, dated April 24, 2015.
(ii) For Model A321 series airplanes: Messier-Bugatti-Dowty Service Bulletin 201-32-63, dated April 24, 2015.
(2) Replace the MLG side stay assembly with a side stay assembly that has been modified in accordance with paragraph (g)(1) of this AD. Do the replacement using a method approved by the Manager, International Section, Transport Standards Branch, FAA; or the European Aviation Safety Agency (EASA); or Airbus's EASA Design Organization Approval (DOA).
Note 1 to paragraph (g)(2) of this AD: Additional guidance for the replacement can be found in Chapter 32 of the Airbus A318/A319/A320/A321 Aircraft Maintenance Manual.
This paragraph restates the provisions of paragraph (h) of AD 2017-13-12, with no changes. An airplane on which Airbus Modification (Mod) 156646, Airbus Mod 161202, or Airbus Mod 161346 has been embodied in production is not affected by the requirements of paragraph (g) of this AD, provided it is determined that no part having a part number identified in figure 1 to paragraphs (g), (h), and (i) of this AD has been installed on that airplane since the date of issuance of the original certificate of airworthiness or the original export certificate of airworthiness. A review of the airplane maintenance records is acceptable to make this determination, provided that these records are accurate and can be relied upon to conclusively make that determination.
This paragraph restates the requirements of paragraph (i) of AD 2017-13-12, with no changes. As of August 9, 2017 (the effective date of AD 2017-13-12), do not install on any airplane, an MLG side stay assembly having a part number, with the strike number not cancelled, as identified in figure 1 to paragraphs (g), (h), and (i) of this AD, unless it has been modified in accordance with the requirements of paragraph (g) of this AD.
This paragraph restates the provisions of paragraph (j) of AD 2017-13-12, with no changes. This paragraph provides credit for actions required by paragraph (g) of this AD, if those actions were performed before August 9, 2017 (the effective date of AD 2017-13-12), using Airbus Service Bulletin A320-32-1429, dated September 10, 2015.
The aircraft, engines and makers this AD names, by the model designations in its text. A model listed here may still be outside the AD's serial ranges.
